` FILTER FOR LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 554,279, dated February 11, 1896.

Serial No. 542,411. (No model.)

To @ZZ whom it may concern:

Beit known that we, THEoDoRE LINKE and HENRY EGBERT GoULD, citizens of the United States, and residents of New York, in the county of New York and State of New York, have invented a certain new and useful Improved Filter for Liquids, of which the following is a specification.

Our invention relates to an improved filter, which is constructed in such a manner that the water may be drawn therefrom in a filtered state or can be drawn directly without being filtered, and in large quantities.

IYith the faucet-filters heretofore commonly used it is impossible to draw unfiltered water without removing the filter from the faucet; and the Object of this invention is to produce a simple faucet-filter from which it is not only convenient todraw large quantities of unltered water, but in which the act of drawing such unfiltered water will cause the filter to be automatically and thoroughly cleansed, thus rendering it unnecessary to remove the filter for cleansing it.

To these ends the invention may be said to consist in the construction and combination of parts substantially as hereinafter described and claimed.

In the accompanying drawing the figure represents a vertical sectional View of the improved iilter attached to a faucet.

A represents a bulb, preferably of glass and of the shape shown.

B is a cap having the flange b and a central opening b2 provided with a screw-thread, and also provided near the edge with another screw-threaded opening, by means of which the filter is attached to the faucet.

C is a goose-neck having a thread at one end7 by means of which ittis attached to the cap B in line with the pipe D, which latter is a perforated section of'pipe having a screwthread, by means of fwhich it is attached to the cap B. The oth/er end of the pipe D is closed, or has a pluO' d inserted therein, and is externally screw/threaded to nt the thread of the upper end of the perforated pipe E. This pipe E is provided with an external thread at its lower end, and is provided with a guide cross-bar e having a square guide-hole to receive the pin f of the valve v.

g is a collar having the milled or polygonal flange g and an internal thread at its upper end and the shoulder g2 at or near its lower end. The eXtreme lower end is inverted-cone shaped and forms a seat for the valve r. The valve c has the square extension or pin f, which fits into the square hole of the crossbar, and has also the threaded stem i.

u is a nozzle having the shoulder n', which fits around the shoulder g2 of the collar g, and is also provided with the threaded guide crossbar n2 and has a flange-wheel by which it may be turned.

F is a filtering medium preferably of natural stone, but which may consist of any artificial material. It maybe of any convenient shape; but we prefer to make it fiat at both ends.

In assembling the parts the pipe D is inserted in a hole cut through the filteringstone E. Then the cap B is fastened by means of the central threaded hole b2 being secured on the pipe D. Between the perforated pipe E and the filter a washer is placed, and the filter is set by screwing up the pipe E. Then the glass bulb A is slipped over the whole, and the edges impinging on a washer placed between the cap B and the bulb. Then awasher c3 is placed next to the bottom of the glass bulb on a seat provided for that purpose, and the square pin of the valve is putin place and the collar g and its attached parts are screwed on. The filter isthen ready to be placed on the faucet by fitting the screw-threaded hole b of the cap to the end of the faucet. Finally the goose-neck C is screwed to the pipe D.

IVhen it is desired to use ltered water, the nozzle is screwed up tight, and thus the valve e is closed. Then the water is forced inward through the filter and passes up through and out of the goose-neck in a very clear and brilliant state. NV hen it is desired to draw a quantity of unfiltered water, it is only necessary to turn the nozzle and the water will ow out, while at the same time the agitation and rapid current of the water will cleanse the ltering-stone- When the bulb is to be cleaned or emptied of accumulated matter, it will only be necessary to open the nozzle to allow it to escape, the outlet being at the bottom of the bulb.

It is to be understood that we are not confined to the use of the nozzle herein described and illustrated, since a common faucet or pet- IOO the bulb A, the perforated pipe D inserted through the same and inclosed in the stone iilter F, the cap B having the central opening` to receive the goose-neck and the side opening by means of which the whole may be attached to a faucet, the perforated pipe E connected to pipe D and passing through the bottom of and outside of the glass bulb and a Valve or cock screwed Jthereto, all arranged substantially as and for the purpose set forth.

Signed at New York, in the county of New York and State of New York, this 15th day oi zo March, A. D. 1895.
